| 摘 要： | 以大叶芹为试验材料,根据其原生环境的特点,进行遮荫栽培。结果表明:遮荫能够降低叶片温度,但差别不明显;随着遮荫程度的增加,气孔阻力增加;适度遮荫使细胞间CO2浓度减少;不同遮荫处理下蒸腾速率的趋势基本相同,但各处理在同一时间蒸腾速率的值不同;遮荫可以使净光合速率增加;遮荫使叶绿素含量也显著高于对照。

| Abstract: | Spuriopiminella brachycarpa was cultivated under shade condition in this experiment,in accordance with its features of the primary environment.The results showed that the shade can reduce temperature of leaves,but the difference was not significant;With the increasing degree of shade,stomatal resistance also increased;Moderately shading can reduce CO2 concentration between cells;Trend of transpiration rate was almost the same under different shade conditions,but the value of the transpiration rate at the same time was different;the net photosynthetic rate can be increased because of shade;chlorophyll content was significantly higher than the control. |
